Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipes, and particularly relates to a high-molecular-weight and high-density polyethylene double-wave-peak and double-inner-rib reinforced winding pipe. Background Art

[0002] Municipal or industrial buried drainage and sewage drainage pipes need to have good corrosion resistance. At the same time, because they are buried and the pipe diameter generally needs to be larger, the ring stiffness requirements for the pipe are also relatively large. The wave-wound structural wall drainage pipe is a structure that solves this problem.

[0003] However, when the existing wave crest wound structure wall drainage pipe is in use, the crest is hollow inside and lacks a structure to increase the strength. Therefore, when subjected to greater pressure, the crest is easily deformed and ruptured due to insufficient pressure resistance. The pressure resistance is poor, the service life is short, and it is not conducive to long-term use.

[0004] Therefore, it is necessary to provide a high molecular weight high density polyethylene double wave peak double inner rib reinforced winding pipe to solve the above technical problems. Utility Model Content

[0005] The utility model provides a high molecular weight high density polyethylene double wave peak double inner rib reinforced winding pipe, aiming to solve the problem of poor pressure resistance and short service life of the existing wave peak winding structure wall drainage pipe proposed in the above background technology due to the lack of structure for increasing strength.

[0007] Preferably, the plurality of steel wires are all high-strength steel wires.

[0008] Preferably, the volume of the first wave peak is greater than the volume of the second wave peak.

[0009] Compared with the related art, the high molecular weight high density polyethylene double wave peak double inner rib reinforced winding pipe provided by the utility model has the following beneficial effects:

[0010] Compared with the relevant technology, the high molecular weight and high density polyethylene double peak and double inner rib reinforced winding pipe of the utility model adopts innovative means such as high-strength steel wire reinforcement, differentiated peak design and high molecular weight and high density polyethylene materials, which has achieved the purpose of significantly improving the pressure resistance and corrosion resistance of the drainage pipe body as a whole.

The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned figures are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0015] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0016] The utility model embodiment provides a high molecular weight high density polyethylene double wave peak double inner rib reinforced winding pipe, such as Figure 1-Figure 2 As shown, the high molecular weight high density polyethylene double wave peak double inner rib reinforced winding pipe includes: a drainage pipe body 1, which is extruded from high molecular weight high density polyethylene, and the drainage pipe body 1 includes a first wave peak 101 and a second wave peak 102, a first reinforcing rib 2 is arranged in the middle of the first wave peak 101, and a second reinforcing rib 3 is arranged in the middle of the second wave peak 102; a plurality of steel wires 4, a plurality of the steel wires 4 are embedded in the first wave peak 101, and a plurality of the steel wires 4 are used to enhance the compression resistance.

[0017] In this embodiment, the drain pipe body 1 is extruded from high molecular weight high density polyethylene. This material has excellent corrosion resistance and mechanical properties and is very suitable for manufacturing underground drainage pipes. The high molecular weight high density polyethylene not only has good chemical corrosion resistance and can resist the erosion of various chemical substances in sewage, but also has excellent anti-aging properties and can maintain its original physical and chemical properties for a long time; secondly, the design of the first wave peak 101 and the second wave peak 102 in the drain pipe body 1 not only increases the ring stiffness of the pipeline, allowing the pipeline to withstand greater external pressure, but also improves the compressive performance of the pipeline. The design of the wave crest structure enables the pipeline to effectively disperse and resist pressure when it is subjected to pressure, thereby reducing the risk of deformation and rupture of the pipeline; furthermore, a first reinforcing rib 2 and a second reinforcing rib 3 are respectively arranged in the middle of the first wave crest 101 and the second wave crest 102, and the addition of these two reinforcing ribs further enhances the compressive resistance of the wave crest; finally, a plurality of steel wires embedded in the first wave crest 101 not only further enhance the compressive resistance of the drainage pipe, but also improve the overall strength of the pipeline. As a high-strength material, the steel wire is embedded in the wave crest, which can effectively improve the compressive resistance of the wave crest when it is subjected to pressure, thereby preventing it from being deformed and ruptured due to insufficient compressive resistance.

[0018] In a further preferred embodiment of the present invention, the plurality of steel wires 4 are all high-strength steel wires.

[0019] In this embodiment, the use of high-strength steel wire means that the steel wire 4 has higher tensile strength and yield strength, and can maintain its shape and integrity under greater pressure. Compared with ordinary steel wire, high-strength steel wire can better resist external pressure, reduce the risk of deformation and rupture of the pipeline when under pressure, and help to extend the service life of the drainage pipe.

[0020] In a further preferred embodiment of the present invention, the volume of the first wave peak 101 is greater than the volume of the second wave peak 102 .

[0021] In this embodiment, by increasing the volume of the first wave crest 101, the first wave crest 101 can more effectively disperse and withstand pressure when the drain pipe is subjected to external force. A larger volume means a larger contact area and stronger structural support, thereby improving the pressure resistance of the entire drain pipe. The volume of the first wave crest 101 is larger than that of the second wave crest 102. This differentiated design makes the drain pipe more reasonable in structure and also helps to improve the ring stiffness of the drain pipe, so that it can better cope with various complex geological conditions and external pressures.

[0022] To sum up, compared with the relevant technology, the high molecular weight high density polyethylene double peak double inner rib reinforced winding pipe of the utility model adopts innovative means such as high-strength steel wire reinforcement, differentiated peak design and high molecular weight high density polyethylene material, which achieves the purpose of significantly improving the pressure resistance and corrosion resistance of the drainage pipe body 1 as a whole. The drainage pipe body 1 is not only structurally stable, durable and reliable, but also can effectively cope with complex and changeable underground environments and installation conditions, reduce the risk of pipeline damage and maintenance, and has a good use effect.
